You need this to clean your espresso machine.
Yeah, you do need to clean it sometimes with something more than just water.
A quick story – I had a client one time that had a new machine from me. I asked him again and again when I could train his team (which includes machine cleaning).
He kept putting it off, and after 3 months BOTH group heads stopped working. It took me over six hours to take the damn thing apart and clean it myself…
Very unsexy job to do… and his equipment was down for a period of time and he lost sales.
I doubt you have time to waste cleaning a machine for an entire day – so go ahead and buy this bad boy.
